    简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 -J{Dxz  
    y#&$ f  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: W^003*m~~K  
    enableservice('AutomationServer', true) n}=rj7  
    enableservice('AutomationServer') 4}+xeGA$  
    kV_#9z7%  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 Z+r%_|kZ  
    bd,Uz% o_  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: ,Y$F7&  
    1. 在FRED脚本编辑界面找到参考. ,tcP=f dk]  
    2. 找到Matlab Automation Server Type Library 7WgIhQ~  
    3. 将名字改为MLAPP JL?Cnk$!

    在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 *Kp}B}}J

    1. 创建Matlab服务器。 N$C{f;xV  
    2. 移动探测面对于前一聚焦面的位置。 oG+K '(BB  
    3. 在探测面追迹光线 _{lx*dq  
    4. 在探测面计算照度 Jq=00fcT+  
    5. 使用PutWorkspaceData发送照度数据到Matlab g@<sU0B  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 gCg4;b6g  
    7. 用Matlab画出照度数据 Y0@'za^y  
    8. 在Matlab计算照度平均值 c9\B[@-q  
    9. 返回数据到FRED中 8.*\+nH
